Science in the Service of Man | English Essay

   Albert Einstein, a German-born U.S. physicist says:

Knowledge resembles a statue of marble which stands in the desert and is continuously threatened with burial by the shifting sands. The hands of science must ever be at work in order that the marble column continues everlastingly to shine in the sun.

Thus science is a persistent pursuit of knowledge, skill, and enlightenment. It reveals sheer truths, mere facts, and bare realities of the universe. It is based on an observation of the fundamental laws of nature. Through its permanent quest, it has opened up new and novel horizons of discovery and invention.

Its enormous impact on agriculture, industry, medicine, astronomy, navigation and traveling is exceedingly amazing. It has proved to be the most trusted and entertaining friend of humanity. It has doubled and multiplied human efficiency and comfort with its vast range of applications and innumerable inventions.

It is human nature to explore new horizons of nature. Man explores the undiscovered and unseen recesses of nature to satiate his unquenched thirst for knowledge. Man will always continue to discover the secret aspects of the cosmos. And it is the science that helps man to accomplish such pursuits.

Life is a constant struggle for survival where man has to toil unceasingly to provide himself with the basic facilities of life. In the past, man had to sweat blood to meet his simple needs. His life was quite uncertain and unsafe. He had to struggle for food, shelter, and security. He had to defend himself against the wild beasts and the odds of life.

Now he has invented powerful weapons to defend himself and his country. With the help of science, he has succeeded in securing a safe home. There is no need for digging holes in the earth to live. Man has built skyscrapers and graceful buildings for this purpose. Even in the house, a woman needs not work with her hands.

She has a spacious decorated house, a well-furnished kitchen, and numerous pieces of equipment to do her domestic duties. As far as food is concerned, man grows all kinds of crops and vegetables throughout the year. He is no more afraid of hunger and famine.

He has invented huge and reliable machines to perform his task in the fields. These machines do their work with magical quickness and accuracy. All this has become possible due to science.

Bertrand Russell, in his book, ‘A History of Western Philosophy’ says:

Almost everything that distinguishes the modern world from earlier centuries is attributable to science.

In the past, man had to travel on foot. Now travel has become a pleasure for him. Swift and speedy means of travel are easily available. He can travel around the world just for pleasure. He had got the better of birds in flight.

He is no more grieved to say goodbye to his relatives and friends. He can meet them and visit them whenever he likes. He has invented more speedy airplanes than sound. By then, he can cover long distances in the twinkling of an eye.

Aeroplanes, trains, buses, and cars are to carry him anywhere across the country. All these quick means of transportation are the result of science. Probably it was this kind of travel about which John Keats once said:

Ever let the fancy roam, pleasure never is at home.

Science has provided us with many means of information, entertainment, amusement, and fun. TV, Radio, VCR, Dish antenna, Cinema, and Computers all are sure means of entertainment and recreation.

The computer and other prompt means of communication have converted the whole world into a global village. Now man can enjoy any sort of extravaganza at any time and at any place.

He can enjoy an activity being performed thousands of miles away around the world. Science has performed wonders in the field of medicine. Diseases like tuberculosis, smallpox, and cholera are no more fatal and deadly. Now plague and epidemics have been controlled. Wonderful drugs have been discovered to the man of pain and diseases.

Antiseptics can kill the germs that spread diseases. The most bewildering achievement of science in this regard is that it has given man a scientific outlook and rational approach to comprehending the mystic of nature. In the field of surgery, science is touching the zenith of progress. Walt Whitman, a U.S poet recites:

Of physiology from top to toe I sing. (Leaves of grass, ‘I Sing the Body Electric)

In short, science is a great blessing which has proved to be useful in all fields of life. It has brought all the nations on one Platform, This age of illumination is different from the age of darkness only because of science. Science has even enlightened us spiritually as it has broadened our views and outlook. We have begun to perceive the laws and the phenomena of nature adequately.

Science in the Service of Humanity: The Astonishing Contributions of Siegfried Engelmann

Shepard barbash.

West Islip, USA

A pioneering scientist and educator for more than 50 years, Siegfried (“Zig”) Engelmann was among the first to apply the scientific method to the design and delivery of instruction. He stood alone for his ability to create programs that accelerate learning in even the hardest to teach children and that most teachers can learn to use. He wrote or cowrote more than 100 curricula, covering the major subjects from preschool to high school. As a professor of education at University of Oregon and founder of the National Institute for Direct Instruction, he attracted students from around the world. No one did more to help the underdog. Millions of poor children learned when taught by teachers trained in his methods, often when nothing else worked. He never gave up on a child or blamed children for the failings of adults. He lived by his motto: “If the student hasn’t learned, the teacher hasn’t taught.” More scientific evidence validates DI’s effectiveness than any other mode of teaching. I will present an overview of Zig’s life and achievements.

Zig Engelmann came from a rough section of Chicago. When he was 15 he lied about his age and got a job at a steel plant, stacking plow disks that came white-hot out of the furnace. Years later Engelmann wrote that “the person who may have influenced me most, who taught me how to think straight and solve difficult problems” was a fellow worker at that plant, an African American named Joshua Baker (Engelmann, 2017 ).

So it’s perhaps fitting that upon Zig’s demise, the most perceptive tribute to his genius came not from a fellow educator, or scientist, or professor in North America. It came from an aborigine in the northernmost tip of Australia, the great advocate for indigenous peoples there, Noel Pearson.

Writing in The Australian the week after Zig’s death, Pearson declared:

Among the lauded educational theorists of the 20th century—Dewey, Piaget, Friere, Vygotsky—Engelmann was the greatest. His seminal work, Theory of Instruction (Engelmann & Carnine, 1982 ), is the educational equivalent of Isaac Newton’s Principia Mathematica or Charles Darwin’s Origin of Species , a first-principles description of the science and logic behind direct instruction. If ideology continues to deny the benefit of his pedagogy to the children who so require it, the science underpinning Engelmann’s art of effective teaching will stand the test of time regardless. (Pearson, 2019 )

The science underpinning Engelmann’s art is a wonderful phrase because it distills the essence of Zig’s enterprise. Of course, his list of discoveries and inventions rivals that of any great scientist . But Engelmann’s programs are also works of art —not only in the beauty of their design and organization of knowledge, but in the artistic demands they make on anyone who tries to use them. Teaching is acting, he often said. He meant it as a compliment. Zig’s adherents are even more metaphorical. One likens DI to a dance between the student and teacher, a dance that the teacher leads (V. Vachon, personal communication, 2011). Another refers to the rhythm of mastery—that distinctive sound of a roomful of children being taught to mastery in a DI school (C. Schneider, personal communication, 2020).

Now all this would seem a long way from toiling in 110-degree heat at an Ingersoll steel mill. And indeed it was. Like Odysseus, Homer’s hero of many twists and turns, Zig found what became the outlet for his genius not straightaway, but after an epic series of adventures and misadventures. His grandmother called him the Wunderkind (T. Engelmann, personal communication, 2011), but if the stamp of greatness was upon him, it was probably not so evident to others.

In junior high he failed algebra and had to repeat it in summer school. In high school he was proud of the fact that he didn’t read a book. “He thought it was entertaining and showed his prowess to figure out enough by talking to people,” his son Kurt said (K. Engelmann, personal communication, 2020). “He told me he was a big bull-shitter,” Kurt’s twin brother Owen said. “He got fairly decent grades, but he confided in me that inside he knew he didn’t know anything, that he was a fraud” (O. Engelmann, personal communication, 2020).

He did show prowess as a cheat. Kurt says:

He was the stage manager for the school’s theatrical productions, which among other things meant that he had a master key that would get him into anywhere in the building. And so he would go into the offices of teachers and steal the exams and look at ‘em the day before the tests. One of his teachers rigged up a camera so that if you opened the door it would take your picture. Somehow he got word that that was going to happen, so he and his buddy dressed up as Donald Duck and Mickey Mouse and went in there and still stole everything. (K. Engelmann, personal communication, 2020)

“My dad was a bit of a lady’s man,” Owen says, “and the gal who tipped him off was one of the assistant secretaries in the office” (O. Engelmann, personal communication, 2020).

He must have been popular. Among other things, as a teenager he taught weightlifting to the neighborhood kids—his first known attempt at systematic instruction (O. Engelmann, personal communication, 2020).

He got into endless scrapes. “He came from a place where there was conflict all over,” said Kurt.

It was a fighter atmosphere, of male dominance to a very high degree. We heard story after story. They were almost folkloric. It started when he was 10 years old, and his brother Monty, who was 12, got beat up at school. My dad went over to the guy’s house and hit him in the face and beat him up, even though he was older. In high school, he played football; they’d practice on this gravelly dirt field. He said he always looked forward to the away games because you would get to play on grass and beat up pansies. (K. Engelmann, personal communication, 2020)

The story of his first foray into book learning sounds a bit folkloric as well. Owen said:

He got this job at a plant where an alarm would go off and one object would come down and he had to choose which conveyor belt it went on, but he’d have 20–30 minutes at a time when he wasn’t doing anything. And so he decided he was going to get smart, and he read the dictionary—the whole dictionary. He knew tens of thousands of words. (O. Engelmann, personal communication, 2020)

I suspect he at least got through the As, because when I sent him a draft of my first piece about him, he commented that some of my sentences were anfractuous —characterized by windings and turnings, sinuous, circuitous (Zig Engelmann, personal communication, 2008). He brought clarity to whatever he put his mind to and was the best editor I ever had.

But of course the big question back then was, what should the young lad put his mind to? He was a good auto mechanic and—no surprise—a great boxer: runner-up in the Midwest heavyweight Golden Gloves tournament one year. He once confided to Kurt that he was made to be a blue-collar worker, and that he related most to people who worked with their hands (K. Engelmann, personal communication, 2020).

Zig’s tribute to Josh Baker, one of the last things he wrote, concludes:

I have very vivid memories of Josh, what he did, and the messages he conveyed to me. Over the years, I've tried to think in the manner he taught me to think. I have tried to make work something I look forward to. And I have faithfully followed his maxim that big pictures are composed of details, and the only way to engineer the big picture is to become aware of all the details and configure them so they work harmoniously together. Thank you, Josh. (Engelmann, 2017 )

On the other hand, after his last book, Could John Stuart Mill Have Saved Our Schools? (Engelmann & Carnine, 2013 ), near the end of his life, he told Kurt that “ Aristotle was his measure, that he had always wanted to produce a body of work that was equal to or exceeded Aristotle’s —and that he was satisfied—he thought he had done it” (K. Engelmann, personal communication, 2020).

The factory worker and the philosopher. That was Zig: drawing knowledge and inspiration from disparate sources, seeing common threads where others saw only difference.

His path was anfractuous. He went to the University of Illinois, dropped out, worked on oil rigs in Texas and at a warehouse back home, talked his way back into college, played football, dove on the diving team—and graduated with honors in philosophy. He sold cars, edited a children’s encyclopedia, sold his services as an investment advisor, then went into advertising (Barbash, 2012 ).

His final turn was an odd one. The president of a candy company wanted to know how many times kids would need to be exposed to a sales pitch for a chocolate bar before they remembered it well enough to go buy it. Zig surveyed the research on learning and memory and found nothing that helped him answer the question. He set up a class to see what it took to teach kids different slogans and became enthralled by the bigger question—how can we help the mind learn? He began teaching Owen and Kurt, and made a short film of them solving linear equations as 4-year-olds (Barbash, 2012 ).

Confident he’d be able to find work writing educational programs, he quit his advertising job, shopped his film to 26 publishers, and was ignored or rejected by them all. He was finally hired as a research associate by the Institute for Research on Exceptional Children at the University of Illinois. This was 1964 (Barbash, 2012 ).

Direct Instruction grew out of an experiment he did that summer to see what young children could learn when taught with the same techniques he had developed teaching his sons. His goal was to show that all children, not just the precocious, could learn much more and much faster than the psychologist Jean Piaget had predicted. For the next half century, he demonstrated that and much more (Barbash, 2012 ).

I describe many of his discoveries and accomplishments in my book Clear Teaching , in the chapter “Engelmann Did It First, A Pioneering Scientist in the Field of Education” (Barbash, 2012 ).

He was the first to figure out that to learn to read one must first be able to hear and manipulate the sounds that make up words—a skill others recognized only decades later and gave a fancy name: phonemic awareness. He was the first to appreciate the significance of the language gap between middle-class and poor students (a gap quantified by Betty Hart and Todd Risley 30 years later), and the first to create programs that enabled teachers to close it. He is one of the unrecognized pioneers of modern cognitive psychology—the study of how the mind thinks, learns and remembers. Scholarly literature today is filled with findings that explain and justify what Engelmann put into his programs forty years earlier. Developmental Psychology, for instance, reported the results of a study showing that the ability to understand and follow directions predicts the ability to learn math. Engelmann’s very first program, Language for Learning , written to bridge the language gap, teaches children to pay close attention to the teacher by giving them tricky commands like “When the teacher says ‘Go!’—stand up” or “If the teacher says ‘Now!’—hold up your hand.” Children also learn to follow sequences of directions like: “Take your coat off, hang it up, sit down, and take out your book.” Engelmann’s first math programs anticipated research showing the sequence by which young children develop number sense. His reading programs anticipated the discovery that comprehension depends on background knowledge, general language skill (not simply vocabulary), and the ability to decode words fluently. They also anticipated findings on the amount of practice needed to learn and remember new words. Engelmann was also ahead of the research showing that students are more motivated to work hard when they are set up to succeed and when they can see that they are making progress on meaningful tasks. Response to Intervention, touted as a major advance in how children are diagnosed and taught for special education, reinvents another Engelmann wheel. Engelmann’s first pre-school did much the same thing RTI purports to do, fifty years earlier, with greater scientific rigor and without labeling any child disabled. Another new tool, magnetic resonance imaging, vindicates Engelmann’s abiding faith that the human mind is malleable and magnificent. MRIs have shown that scientifically-based instruction like DI produces lasting and beneficial changes in the brain, thereby confirming in the lab what Engelmann found through logical analysis and experience in the classroom. (Barbash, 2012 )

The last chapter in Clear Teaching , Great Teachers, summarizes his achievements.

Engelmann’s mark on education, though it might have been larger, has not been slight. He analyzed three of the most complex subjects—oral language development, writing and math—and created the tools to teach them systematically, even to low performers. He made educators aware of the importance of curriculum. He showed that poor and disabled children can learn at reasonable rates using standard levels of funding, and that it is therefore fair that we hold ourselves accountable for their learning. He showed that student behavior is inseparable from instruction: the better the instruction, the better students behave. He showed that teacher quality is inseparable from curriculum: the better the program, the better teachers teach. He disproved the stereotype that learning must be painful and full of furrowed brows: good instruction turns learning into a game students can win. (Barbash, 2012 )

One thing Clear Teaching missed was Engelmann’s profound impact on the field of behavior analysis. He showed us that if you want good behavior, you have to teach it. Zig’s coauthor and close friend Geoff Colvin tells me that “if you grabbed a discipline manual from the 70s, you’d see: ‘Here are the rules, here are the negative consequences for breaking them.’ The emphasis now is on establishing the behaviors you want up front. That’s a paradigm shift,” Colvin says—from consequences to antecedents, from managing behavior to anticipating it (G. Colvin, personal communication, 2020). Positive behavior support, an outgrowth of Engelmann’s work, is taught today in 21 countries and 74 languages (R. Horner, personal communication, 2020).

Zig also reminded us that inappropriate behavior is not innate: it’s learned, like most everything else—which means that to correct it we need to figure out why kids misbehave the way they do, what they’re really after, and then, whenever possible, teach them a more appropriate way to meet their needs.

Most important, he showed that the best way to teach good behavior is by using the same principles and techniques that we use to teach academic skills—or the violin, or weightlifting, or football. If you want your kids to be orderly going to the library, show them how and practice it—same as you do when you want them to read a word correctly. He resembled Einstein in his search for a unified theory of teaching and learning.

When developing programs he would often ask, “What’s the rule?”—by which he meant: what is the idea we can use to explain the biggest chunk of content possible, thereby organizing the subject for the teacher and reducing the memory load on the student. Thus in earth science, one rule might be: when something gets hot it expands. This helps explain everything from the formation of continents to the vagaries of the weather.

Zig may not have invented the science of instructional design, but he advanced it farther than anyone ever has. And unlike Newton, who had his Kepler, or Aristotle, who had his Plato and Socrates, Engelmann had no obvious forebears. Besides thanking Josh Baker, Kurt says his dad credited his college roommate, a guy named Shelby, for teaching him how to read critically. That’s it. No one else. Shelby became an electrical engineer (K. Engelmann, personal communication, 2020). Kurt says:

Zig really admired the hard sciences and lamented the social sciences. He explained to me one time very visually that the hard sciences were moving upward like a sloping line that over time were always building upon each other. The social sciences were simply vacillating back and forth between one extreme and another and not moving forward. And he admonished all of us not to follow his footsteps, and to go into the hard sciences instead. In education it was just so difficult to build on a body of work, and to show progress in your own work. That’s one of the reasons he loved manual labor—not just for the exertion, but for the satisfaction of seeing what you’ve done with your labor. (K. Engelmann, personal communication, 2020)

Zig also lamented the narrowness of our senses. Kurt recalls him once launching into a discourse on the electromagnetic spectrum and all the light we can’t see, and then on vibrations and all the sounds we can’t hear. He grabbed a pillow. “This!” he cried. “This pillow vibrates and makes a sound! And I can’t hear it!” Kurt says it was almost as if he was doing a monologue in a play about the frustrations of the limitations of our existence, of how little we know. He envied dogs their sense of smell. He loved hounds (K. Engelmann, personal communication, 2020).

If something interested him, he would take data on it with almost freakish intensity. On his morning commute, for instance, Kurt says he would count and memorize how long the different stoplights were green and how many times the white walk sign would flash before it turned to yellow. He knew the data for all the possible routes and he would take the fastest route. “He loved going fast, and the feeling of going fast” (K. Engelmann, personal communication, 2020). He liked motorcycles and boats, and went notoriously fast on both.

One of his core dictums when designing programs was “Do it the fast way.” Of course here it wasn’t about thrill seeking but about satisfying the requirement to be efficient. Zig said to me, in that piece of mine he called anfractuous:

Time is the great enemy of the at-risk child. He must learn more in less time, he is less experienced at learning, and he needs more practice. You can’t reproduce the form of the middle-class upbringing; you’ve got to try to reproduce the function . That means teaching kids the fast way . (Barbash, 2008 )

His programs do that. He wrote or cowrote more than a hundred of them, covering all the major subjects from preschool to high school.

He often referred to himself as a teacher, but he spent most of his time writing. He wrote 6 hr a day for 50 years. As one colleague describes it: “Sometimes he wouldn’t move for hours. He’d just sit at his Remington, kind of furious the whole time, furiously typing. He’d drink dark coffee and smoke cigarettes and eat nothing” (G. Singer, personal communication, 2020). At 3:30 he’d break for beer and peanuts, joined by his coworkers. He’d go home for dinner and come back and write some more. He wrote on weekends.

A typical program took him anywhere from 3 to 10 years to develop, depending on how much field testing and rewrite it required. His ironclad rule was that every student would learn everything in the program, and that the average teacher would be able to teach it.

There’s a Buddhist saying that mountains make their own weather. Zig certainly made his. He inspired people around him to do remarkable things. “He didn’t just teach us how to teach,” one of his students said. “He taught us how to look at the world” (J. Sherman, personal communication, 2020).

He may have been in Darwin’s league—he told me that Darwin was the person he most identified with (S. Engelmann, personal communication, 2010). But what made him sui generis was that he was a great thinker and a great observer and a great inventor and a great teacher. His Theory of Instruction may have only been read by a few thousand people, but his programs have been used to teach millions—and not just any millions, but our most vulnerable and least fortunate millions, overwhelmingly children.

For Zig, it was always about the kids. The last thing he would see as he lay dying, he said to a friend, were the kids (G. Singer, personal communication, 2020). He gave them his life so that their lives might be better.

Science Is The Service Of Man (Essay Sample)

“Truth”, is the original meaning of the word which the word Science came from. It is common knowledge that all this time scientist have been chasing the knowledge explained and expounded by the scientific method because they believe that science is a field of study that never depends on opinion thus, regards only a certain one true idea in a certain framework. And this science, is profound to be the service of man in many years even before.

Science have been incorporated to another technical term or the ‘technology’. Technology is the actual application and product being develop by years of study of scientist in their theories then applied in laboratory for test. Science and technology have been existing far beyond the early age of man. It was science when the early man understood the use of fire in order to survive and also when they improve their life using stick and stone. In the preceding years, when man’s civilization was improved, one of the ground for improvements they focus on is science and learning it is because they understood that in order to further improve their society and gain advantage against their enemies they need to have better understanding of resources available to them. Science is the service of man in many terms such as in education, health, and technology. Education is an essential part of social system because it enables the young ones gain learning and proper training in order to engage to the problem that the communities are facing. The role of science in education system kicks-in in the form of academic subject that is divided on different category like general science, biology, chemistry and physics. The following general science topics have been greatly discussed in education, mainly because those topics are the basic ideas that one should know in order to move on intermediate or advance level of learning. Also, these science fields opens the perspective of many people that leads to many discovery and as we all know the living proof of science, as being service to the man, are very obvious around us because our clothes, chair, flooring, walls, gadgets, electricity and over-all most of what we use in daily basis are explained, studied and improved by science. Also, science have been service of man when it comes to health issues. Without science, there would be catastrophe and low mortality rate because mankind have faced a lot of sickness in many degrees like pandemic and epidemic level. Example of this sickness is the widely known as Black plague that claims thousands of lives, but humanity stood still and found the cure of the disease and even if we faced the new generation of sickness we have still been able to find solution on how to cure them, Moreover, science have been proven itself on technology side when it comes on developing the communication, transportation and human understanding of environment and human nature itself. Science, based upon on current news and events, have put mankind into another milestone, as it opens the digital age. In digital age, science have applied its theories into practical application making the gadgets of today fast and reliable like the wireless handset we used in communication and the upgrade of transportation that we used like the vehicles, trains, ships and airplanes.

To sum it up, it once said that ‘necessity is the mother of all invention’, it is without a doubt, that we humans are changing and the things we need also need to cope up on our needs and for us to get our hands on things we need there is the science that will be service to the man.

Science in the Service of Man

Essay No. 01

Facsimile (Fax)—Facsimile transfer of messages i.e. is used for transmission of weather charts, engineering drawing and even hand written notes. It transfers copies of any types of document written in any language and in any script with a great speed. The Fax employs a photo-scanning process to obtain its electrical signals which are then transmitted through the communication channels at the receiver end, the message is automatically printed on a laser printer. The equipment in which the document is placed is called POTS.

Pager—It provides one way wireless communication to the wandering users. In this system, the messages are sent to the subscribers which consist of a small receiver. The messages that can be sent are of three types.

(a) Only ton beep is given

(b) Numeric message—in which the telephone number of the cellar is transmitted to the subscriber (i.e. receiver) and

(c) Alpha-numeric message in which the message in alphabets numerals is transmitted. The cellar calls the base station (B.S.) and gives them message and destination cellphone or pager number. The base station then sends the message to page subscriber through wireless technology. The receiver units responds to a short burst of coded signals of beeping and activating a vibrator to indicate that he is wanted.

LASER— The name LASER is an acronym for light Amplification by Stimulated Emission of Radiation. A Laser is an electric apparatus for producing unified light waves that can be exactly controlled, precisely focussed and when desired made extremely powerful. It can be aimed precisely enough to destroy dangerous skin tumours without affecting healthy skin tissue. Laser light has certain remarkable properties which make it chromatic, for example, a red laser beam has only red light. Laser is very coherent and can be transmitted over great distances, without the beam spreading. It also has the advantage that a lot of power is concentrated in a very small area. Sunlight electric light and the light from a candle is incoherent. It is a jumble of different wave length and brightness in what seems to a steady light emitted in every direction. To produce a coherent beam, the original light has to be coherent and that is what a laser does.

Initially, the lasers used rubycrystals and were not very powerful, fairly expensive and unwieldy. The present day lasers come in all sizes ranging from the micro-lasers to the huge lasers used for fusion research.

Robotics— Robotics is the study of the design and use of robots (Czech; robot meaning compulsory service) i.e. the machine programmed to carry out a series of operations without human guidance. The word Robotics was invented by Isaac Asima. Industrial application of robots is favoured because of their untiring nature, predictability, precision, reliability and ability to work in relatively hostile environment. Besides robots frequently increase productivity, improve overall product of quality, allow replacement of human labour in monotonous and of course in hazardous task. Computer controlled robots are used in industry to do welding, assembling and machining and to handle various materials. Non-industrial applications of robots include marine space work bionomics, form work, helping the disabled, lab work, mining, nuclear work, security guarding simulation, warehouse, microsurgery etc.

Polymorphic Robot – Recently the scientist have developed a polymorphic robot, which can change its shape according to the job that it is assigned to. The thermoplastic framed robot is being developed by HodLipnn with Jordan Pollock. The basic idea is to assign the robot a particular task, and then a computer would attempt to design a specific body, which would facilitate the robot to meet this challenge with efficiency.

RADAR—Acronym for Radio Detecting and Ranging (RADAR)—a technique and apparatus for determining in the location of an object by the use of radio-waves. The most visible and ubiquitous aspects of radar are the rotating curved surface, antennas seen on the top of most ship and airport towers. Not visible but equally important are radar antennas hidden in the noses of aeroplanes.

It is a system employing microwaves for the purpose of locating identifying, navigating or guiding such objects as ships, aircrafts missiles or official satellites. It can determine the direction, distance, height and speed of objects that are not visible to the human eyes.

Application– Radar has a large variety of applications involving precise measurements of distances. Besides being used for navigating ships and aircrafts it is used for mapping stars and other meteorological disturbances, and studying planets and their moons or satellites. It is used for determining altitudes, aeroplane navigating in fogs and in the dark. A useful application of radar is for police speed trap. Here a special radar device is used which responds differently to the reflections from moving objects and stationary objects.

SONAR — Acronym for Sound Navigation and Ranging (SONAR)—a technique and apparatus for determining the location of an object by reflected sound-waves. In fact it is a system for detecting and locating submerged objects or communication underwater by transmitting high frequency sound wave and collecting the reflected wave. The Sonar principle is used to determine the depth of shallow bodies of water and to locate fish under water submarines. Initially developed as a military instrument for locating submarines, it is widely used for measuring water depth and in Arctic regions for measuring ice-thickness.

In Active Sonar pulses of high frequency (high pitched) sounds are beamed downwards and at angles from the bottom of a ship. The echoes are received by an apparatus that measures the time interval, then computers the distance and frictions of the reflecting object. This information is shown on a dial, or plotted automatically on a chart. Passive Sonar does not send out sounds. It detects sounds made by submarine engines or other sound producing objects.

Science in The Service of Man

Science has opened and enlarged new frontiers of human knowledge, information, achievement, comforts and conveniences. Now we have a window, large enough to peep into the hitherto unknown, dark and mysterious areas of nature in the form of modern science. This passage from ignorance to knowledge, from darkness to light, from superstitions and blind beliefs to scientific temper and rationality, has been a long struggle, full of strife, labour, sweat and challenges. But it is man’s nature to seek and face challenges and his destiny to overcome them.

Man’s endless thirst for knowledge and conquest has resulted in phenomenal advancement of science in each and every walk of life and so the modern age has rightly been christened as the Age of Science. Science means reasoning, analysis, objectivity and systematic study4of things. Science is very comprehensive, universal, all-inclusive, simple and yet very complex and so beyond the approach of a satisfying definition. It may not be defined but touches all of us at all the places and times. Its expression is universal, unambiguous and palpable and well understood by the educated people in most of the cases. People know that science has helped man to conquer time and space and the world has turned into a global village. Now, the moon is in the palm of his hand and planets are not too far off for his scrutiny and study. We have supersonic planes and will soon have hypersonic planes to enable us cover the distance between Tokyo and New York in just 2 hours. Satellite communication has ushered in instantaneous contact from one corner of the globe to another. Instant communication through cordless, cellular and mobile telephones, paging, and electronic mail, etc. are really wonderful. Then there are computers, which help retrieve any information you require from anywhere in the world. Satellites have also revolutionised our world of entertainment through dish and cable T.V. Science has completely changed the face of the earth and the outlook of man. So much so that if one of our forefathers were to come alive, he would not easily recognize either the place or his descendants. And the march along the path of progress, past milestones of achievements, is on in the vehicle of science. The ride is so wonderful, so pleasant and thrilling that it makes one forget his vital breath for a moment.

Life has become so easy, convenient and comfortable because of our scientific achievements. Science is a powerful weapon and it is up to man how he uses it. Science is neither a blessing nor a curse in itself. It is knowledge—pure, powerful, universal and absorbing—always at our service, command and bidding. Its aim is to serve sincerely but it is our prerogative to decide what service we ask science to render. Therefore, it is unwise to categorise science as evil or good.

Science has helped us in eradicating many diseases, which were fatal in the past, and in treating many others. Now transplantation of many vital organs is a common medical practice. As a result of many medical discoveries and inventions, man finds himself more safe, secure and his age lengthened. It is because of many scientific teachings and learning-aids that distant education is so popular, cheap and universal. Science has turned learning into a pleasure.

The wonders and achievements of science are too many. Take for example, the harnessing of nuclear energy. It has broadened the horizons of power to be used to run mills, factories, engines, railways, to light up homes and streets, to energise pump sets and tube wells, to smoothen earth-moving and mining work, to be used in irradiation, to preserve seafood and other food items and sterilization of medicines, to name only a few of the areas. There are many other areas which have immensely benefited by it. It is a great and inexhaustible power with huge potentialities.

Again, the world of scientific appliances is no less wonderful. Now man has more time because of these gadgets and conveniences. Science has helped man to leapfrog into a new, bold and wonderful world of fantastic achievements, comforts and conveniences. No doubt, the other side of the coin shows the darker visage of science. The misuse of science and its inventions has brought the entire humanity on the brink of destruction and annihilation. It has produced very dangerous weapons, like nuclear bombs, missiles, and fatal and poisonous nerve gases, etc., but again it needs to be underlined that science is neither good nor bad. It is knowledge; it is power, a boon and gift, a key to unlock the secrets of nature. If we misuse it, we are to blame.

   Science in the Service of Man

(The following speech is perfect for 1 min. to 1.05 min)

The first scientist was the caveman who picked up a stone to kill a deer- he made something to serve his purpose. Science made advancement in the sharpening of stones to serve as weapons, making fire by striking one stone against another. Man gradually made machines to serve him and today these machines are so much with us that we cannot do anything without them. Science is all around us. We are living in an age of science. It is difficult to think of human progress without scientific inventions. These inventions have brought about a great change in the life of a man. Wonderful inventions in medicine and surgery have made life healthier and happier. Diseases which were considered to be incurable in the past are today easily cured. Plastic surgery and transplant of such vital organs as heart and kidney are of great help. Inventions in the field of transport and communication have conquered time and space. Isn’t it thrilling to watch a cricket match being played in England or Australia in our drawing room telecasted with the help of satellite?

Q. Do you really think that science helps us without any harm? A. Actually, I am partially not convinced with your view as I think that science is a good servant but a bad master and it is up to us that we become the slaves of it or treat it as a servant. Excess of everything is bad.

Science in the Service of Man

Science has rendered a great service to man by exposing the hollowness of several superstitious beliefs and myths, which stifled man’s onward march to progress. Illness was attributed to sorcery, failure of crops -to-angry gods or malignant demons. Human sacrifice was thought to promote victory in war and the fertility of the soil. Eclipses and comets were held to presage disasters. The venerable Bede asserted that “comets portend revolutions of -kingdoms, pestilence, war, winds or heat”. It was Newton and Halley who explained the appearances of comets scientifically. James I was a fanatical persecutor of witches. Even Francis Bacon believed in them. Scientific medicine had to combat superstitions. When Vesalius first practiced dissection of corpses, the Church was horrified. The Emperor Charles V saved him from persecution for a time. On his death, Vesalius was accused of cutting people up before they were dead. He was asked to go on a pilgrimage to the Holy Land. On the way he was shipwrecked and died of exposure. Insanity was thought to be due to possession by evil spirits and was therefore treated by subjecting the insane to cruelties which, it was hoped, the demons would dislike. George III, when mad, was treated on this principle. It is hardly till the time of Lister, and Pasteur that medicine can be said ‘to have become scientific.

As a result of quick means of transport and communication, the world has shrunk. Now we can go to London or New York in a few hours. The telegraph, telephone, radio and television have made communication quick and easy. No country is now an island.

Electricity helps us in many ways. For this we are greatly indebted to Faraday. It helps to make ice and cold drinks and enables us to get up-to-date news every day. It makes the film move and thus gives us so much pleasure when we go to cinema. It is used for broadcasting and many other purposes. In fact, we cannot think of modem life without the blessings of electricity.

Science has made great progress in the field of medicine and surgery. Drugs like penicillin have conquered several diseases. We can now prevent the attack of some diseases by prophylaxis. X-ray, antiseptic surgery and anesthesia have revolutionized surgery. Japanese doctors have, succeeded in making synthetic blood. And, death rate has considerably been reduced.

Agricultural production has increased. We have now intensive methods of cultivation. Tractors, pump sets, new varieties of seeds, and fertilizers, etc. have revolutionized agriculture. In Japan they have hydroponics. Khushwant Singh says everything relating to this has been mechanized. They produce crops round the year, in and out of season.

Good progress has been achieved in the field of industry. The goods required by man are now manufactured expeditiously. The machines invented by scientists have reduced human drudgery in factories.

Nuclear research has made commendable progress. Nuclear power stations now produce electricity in several countries. One pound of uranium is the power equivalent of 2,300,000 pounds of coal. With the help of nuclear energy, brain cancer and tumours can be cured in their initial stages. Radio isotopes are useful to the farmer. Engine wear and lubricant efficiency are also quickly determined by the use of radio isotopes.

Science has helped in disseminating knowledge. The printing press has created a revolution in the field of knowledge. Many newspapers, magazines and books are published. Now man gets knowledge from everywhere.

Science assists in detecting crimes. Dactylography, polygraph and computers do a very good service in this field.

The scientists must realize their responsibility to mankind. The knowledge they have gained must be used only for constructive purpose. If they act in accordance with the whims and fancies of politicians, the future of mankind will be dark.
